Superman watercolor painting by White

This is a piece I have had for years, but because it was damaged during shipping, I put it away and forgot about it. I still really like the image and style, but the crease along the right side, all the way from top to bottom, still annoys me terribly and all because someone couldn't pack artwork. Also, after all this time, I have no idea who the artist is, as this was a random Ebay win. It's signed by White, so that's all I know. It measures about 8 1/2 x 11 on watercolor paper.
